Abstraction

Sixth graders learn abstraction — focusing on the important idea and hiding details you don’t need. A map hides every tree; a function name hides its steps. They explore everyday examples, then use abstraction to simplify a plan.

QUESTION 1
What is abstraction?
Focusing on the important idea and hiding details you don’t need.
QUESTION 2
Why is a map a good example?
It shows the roads you need and hides everything else.
QUESTION 3
How does a function name use abstraction?
You use the name and ignore the steps inside.

Reflect: abstraction.

Have students name one everyday example of abstraction. A printable abstraction worksheet is in the Computer Science library.
